What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Cholangiocarcinoma (CCA) is known for its high aggressiveness and dismal prognosis, whose effectiveness of systemic therapy remains limited. As a multi-target drug, lenvatinib has exhibited promising effects in many solid tumors. However, the therapeutic role of lenvatinib in CCA is rarely investigated. Here, the in vitro assays including EdU, colony formation, transwell, wound healing, and apoptosis analyses demonstrated that lenvatinib significantly inhibited the proliferation, migration, and invasion, while simultaneously inducing apoptosis of CCA cells. Mechanistically, lenvatinib downregulated the expression of FGF19 and inactivated the PI3K/AKT signaling pathway. Depletion of FGF19 enhanced the anti-tumor effects of lenvatinib, which was attributed to the inhibition of p-PI3K and p-AKT expression in CCA cells. In contrast, overexpression of FGF19 activated the PI3K/AKT signaling pathway, thereby impairing the inhibitory effects of lenvatinib against CCA. In addition, the AKT inhibitor, MK-2206, reinforced the lenvatinib-induced CCA inhibition. Notably, the in vivo experiment confirmed that the subcutaneous tumorigenicity of CCA cells in nude mice was weakened by lenvatinib. Lenvatinib markedly downregulated the expression of FGF19, p-AKT, Ki-67, vimentin, and VEGF in the xenograft tumor tissues. Collectively, these findings demonstrated that lenvatinib inhibits CCA progression by targeting the FGF19/PI3K/AKT signaling pathway. The present study provides novel experimental evidence for the potential clinical application of lenvatinib in CCA, which also highlights the promising role of targeting FGF19 in combined therapeutic approaches for CCA.
